Overview
The LM119W-SMD is a high-speed dual comparator manufactured by Texas Instruments, designed for precision applications requiring fast response times. It operates from a single 5V logic supply or dual supplies up to ±15V. The device features an uncommitted collector output capable of driving loads such as lamps and relays at currents up to 25 mA. It offers low input bias current and high gain, with typical performance specifications including an 80 ns response time at ±15V and a maximum input current of 1 µA over the operating temperature range.
Feature Summary
- High-speed operation with typically 80 ns response time
- Uncommitted collector output compatible with RTL, DTL, and TTL logic families
- Capable of driving lamps and relays at currents up to 25 mA
- Low input bias current of 1 µA maximum over temperature
Applications
- Window detector circuits
- Relay driver applications
- Digital logic power supply monitoring
Procurement Notes
Verify the specific radiation tolerance requirements (High Dose Rate vs ELDRS Free) against the application environment. Confirm the package type matches the design constraints, as the LM119 family includes various ceramic packages. Ensure compliance with MIL-STD-883 testing methods if military qualification is required. Check for any specific ordering suffixes that denote material or processing variations.
Selection Notes
Select this component when high speed and wide voltage operation are critical. It provides faster response than older comparators like the LM111 while maintaining versatility across different supply voltages. Consider the higher power dissipation compared to lower-speed devices. Verify that the open-collector output interface meets the system's logic level and drive requirements.
Part Context
The LM119 series is a family of precision high-speed dual comparators fabricated on a single monolithic chip. It is designed to operate over a wide range of supply voltages, down to a single 5V logic supply. The device offers higher gain and lower input currents than similar legacy devices, making it suitable for applications requiring both speed and precision in digital logic environments.
